WATER-'HEATING DEVICE.

Application filed March 14, 1922. Serial No. 543,679;

To on whom it may concem 'Be it known that I, EDWARD CHA-PPELL, subject or" the King of Great Britain, residing at Eagle House, Harleston, Norfolk, England, have invented new and useful Improvements in Water-Heating Devices; and I do hereby declare the following to be a full, clear, and exact description in the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a water-heating device and it has for its object to provide a device of this character which in use is adapted to be placed within the body of water to be heated in contra-distinction to the conventional type of water-heating vice in which the water is caused to flow through the same.

The water'heating device according to this invention comprises a casing which is closedat the top, sides and bottom and contains a suitable gas burner or other heating means whilst the top of the casing is formed with a plurality of narrow spaced passages of any suitable conformation adapted to constitute outlets for the hot air. One of these passages may be so formed that the height of the same is capable of adjustment for the purpose of regulating the air supply ;t'or supporting combustion at the burner.

In order that the invention may be clearly understood an embodiment of the same will now be described by aid of the accompanying drawings in which Fig. 1 is a front elevation of the apparatus.

Fig. 2 is a plan of the same.

Fig. 3 is a sectional elevation on the line 33 of Fig. 2 showing the device immersed in a basin of water.

Figs. 4 and 5 are an elevation and plan respectively of a suitable gas pipe connection.

Referring to the drawings the heating device therein shown consists of a conventional gas ring 1 located within a casing 2 which is closed at the bottom and sides so as to be watertight. The gas for this burner passes in through a suitable valve controlled pipe connection 3 mounted upon the top of the casing the outer extremity of which pipe is adapted to be connected to any convenient source of supply by means of a length of flexible tubing l. In conjunction with the main gas inlet I propose to provide a pilot.

light 5 the flame from which is adapted to strike down into the interior of thecasing through a vertical tube 6. The valves 7 and 8' controlling the gas supply to the gas ring and the pilot light may be interconnected as shown in Figs. 4 and 5 in. such a manner that it is impossible to turn on the gas to the gas ring until the valve controlling the pilot light has been opened. The casing en- I closing the main burner is closed at the top by a plate 9 which is formed with a series of narrow slots extending across the same at spaced intervals which slots are bounded by Walls composed of thin metal so as to thereby constitute a series oi spaced ribs 10 between which the water to be heated is permitted to flow. By this means a large heating surface is provided, it being understood that the hot air from the gas ring passing up through these ribs serves to heat the thin walls of the same which heat is thus imparted to the surrounding water by radiation.

The device may be provided with a suitable handle 11 and the same will be weighted so as to cause it to sink to the required depth within the body of water to be heated.

A device according to thisinvention may be used to rapidly heat up water for a variety of uses for which purpose the Water may be put into an ordinary washing basin 12 and the device stood therein as shown in Fig. 3 of the drawings. p

Air is admitted to the interior of the easing through a central rectangular tube 12 which is provided with a telescoping liner 13. This liner is vertically adjustable for controlling the draught of air and. is secured in the adjusted position by means of a fly nut 1a or equivalent device.

What I claim is 1. A heater of the kind described comprising a casing, heating means within the casing, tubular heat radiating ribs extendingfrom the casing and communicating therewith, and a tube for supplying fresh air to said heating means. said tube being adjustable in length thereby to adjustably control the admission of air to the heating means.

2. A heater of the kind described com prising a casing, heating means within the casing, tubular heatradiating ribs extending from the casing and communicating therewith, and a tube for supplying fresh air to said. heating means, said tube being composed of telescoping sections whereby it is control the admission of air to the heating means, and means to secure said sections in different relatively telescoped relations.

In Witness whereof I have signed this specification in the presence of two Witnesses.
